Beautiful, small and with great power. Either if you're using it on your car or at home, you'll always find a good use for it. No instructions - none. No indication of how to change between the various inputs. No indication of how to repeat, shuffle, or such. Just trial and error, or check the forum to half-answers.
It seems like the last second or so of my songs is being cut off. The remote control are very small and works very good. At the remote control is possible to next or previous musics and control de volume too. And there is another equalizations available to use if you need. Its ugly but fully functional. Give it time to see how well it survives. Read more

It accepts SD cards and USB sticks, and also has 1/4&quot; audio input as well as RCA type inputs. It comes with a typical chinese style mini-remote. It has acceptable audio quality. You can power it off 12 volts easily. I am using it as a standalone mp3 player in my car, before running the output to a hidden amp, and from there to my speakers. If someone steals it, I'm only out a few bucks. This is decently designed and cheaply assembled. I needed to take it apart and oil one of the on/off buttons so it didn't stick. One of the forum posts for this product details an extensive replacement of nearly every single potentially defective electronics component, at an unknown cost. Some of the screws used for a bottom mount section for the circuit board were wood screws. It is not a sufficient amp on it's own, at least not with my speakers. It plays mp3 formats just fine off a stick or SD card. This is basically all I wanted. It's cheap, it works acceptably out of the box, and you can determine how much effort you want to put into it. It's a 12 volt expandable MP3 player for your car / cabin in the woods / ATV, it's an electronics kit for you to tinker with, it's the perfect gift for a hobbyist (although they may resent you at first.)

I have used it for my motorbike (Honda Deauville) Sound is quite good and loud enough. Works on 12 volt using (car)battery or adapter. Sound quality: no cons considering te price. Use: easy, no modification was needed. Blue led is too bright, but that is easily taken care of. I did not have much use for the remote. Power is (much) less, but no problem for my purpose. Perhaps an AM/FM amp with SD slot? Miss the radio. Small adapter will work fine (amp power is less) Good amplifier, very suitable for low-end purposes, such as PC amplifier Motorcycle TV Boat Read more

Mine did work right ou of the box. You can't beat the price, $ 19,00 for an Amplifier with USB and SD card reader, remote control and a good chip like the Tk8205 that can output good soudn quality.

You can't beat the price, $ 19,00 for an Amplifier with USB and SD card reader, remote control and a good chip like the Tk8205 that can output good soudn quality. Like already said low quality components and QC needs to be improved but for $ 20 stills a very good purcahse. I replaced the blue leds for green and white leds and also replaced all the capacitors on mine for sanyo low esr caps and it did improved ALOT the sound quality. If you need an amplifier with usb, sd card line in RCA and remote control for under $ 30,00 tha'ts the one. If you don't care about USB and sd card decoder, remote control and all you care about is T class sound quality then you should search a little more. Read more

Works like a charm!
Sound is loud and clear - I'm running a pair of one-way 4&quot; car speakers and its fine. Would probably do better again with some two or three-way 6x9 speakers.
Mine didn't need any fixing to make it go, maybe I was just lucky. However I opened it and put some thermal grease...Works like a charm!
Sound is loud and clear - I'm running a pair of one-way 4&quot; car speakers and its fine. Would probably do better again with some two or three-way 6x9 speakers.
Mine didn't need any fixing to make it go, maybe I was just lucky. However I opened it and put some thermal grease between the big power transistors and the case, as recommended. Did not need to mod anything.
The SD card reader reads a 4GB SDHC card fine. I was worried it would top out at 2GB SD only cards. Have not tried USB or line in yet.
Bass/Treble/Volume physical knobs do turn and work as expected. They're not decorations.
When power turns on, it auto-plays Butt-ugly. Mine was a slightly reddish tinted mid-grey, so not as pink as the photo.
The blue LEDs are bloody bright - I'll change them to red. No idea what they actually mean.... no labels bro.
No english instructions, and they'd be useful. The remote is *WEIRD* - its important so don't lose it... The volume knob on the front is overridden by the vol+ and vol- on the remote... like there's two volumes in series. There's also a SD/USB button on the remove, and a hard button on the Amp itself... not sure which has priority.
There's no &quot;fast forward/rewind&quot; buttons, just Next and Last track. Big things in the USB port will be in the way if you're going for the volume knob.
SD Card pokes out a bit too
When you power the amp back on the same track plays again from its beginning. Not a bad thing but not a pro either.
The back panel says &quot;12V at 5A&quot; which is 60 W. A kilowatt shows that it draws 0.12 A at 240V starting, and runs at 0.03A. So its using no more than 2.5A No need to get a spankingly big PSU to run it. BTW no power supply comes with the amp, but this is going into my landy.
The remote/IR sensor has an excellent detection angle.
There's no way to delete or mark the current track somehow... I can imagine hitting &quot;next track&quot; a lot. Its ugly but fully functional. Give it time to see how well it survives. Read more

Surprisingly powerful. Quite nice looks. In my opinion looks more pricy (quality) product than 13eur.
More features than needed: SD, USB, remote.
Remote functions are reliable and quick. - Requires the DIY-fix (thanks &quot;lucpeeters&quot;)
- Doesn't include power
- balance issue (***)

- Doesn't include power

- annoying noise comes thru
- Weird squeezy sound on power-up *** I've connected my computer to it and if I turn the volume knob to minimum the sound still comes thru, but only to the left speaker. If I put some volume sound balances to the middle. For the money, it's a great product Read more

Now this amp is doing a fine job of amplifying the sound from my TV into some reasonable speakers. No more thin, kickless sounds... :D - looks great - sounds great - works nicely, has a surprisingly large amount of power available, especially when using sensitive speakers - doesn't produce a great deal of hiss/noise, when TV (or other source) is powered off - Needs a quick mod to get perfect operation A simple-to-implement amplifier that fits the bill in most cases that don't require stadium performance amounts of power.

It seems like the last second or so of my songs is being cut off. Maybe a glitch in the MP3 decoder? I recommend trying your amplifier without opening it. Mine did not have any of the noise that others report. If yours does, then you may want to check the forum.
If you plan on cranking the amp at full volume, then adding thermal grease to the amplifier ICs is probably good advise. I have run this amp for hours at 35% to 50% with no significant heat.
This is the perfect solution for me to use some old speakers to make an audio system for my garage. I just happen to have an old 12V, 4A power supply with 2.5mm coax power plug, too. This amp won't wake the neighbors with window-rattling bass. It will give new life to an old pair of speakers, though. Read more
